Handling & Cleaning The Z-PRO Filters

•

With the exception of the polarizing and Varicolor

filters, Z-PRO filters are made in CR39

organic

glass, an optical material of exceptional quality; virtually unbreakable and extremely long-lasting if they

are handled with care and stored in a case with adequate protection.

It is true that these ﬁlters have proven to be a bit more sensitive to scratching than those made of mineral

glass... But if you drop the latter on a hard surface or the ground, it will be without a doubt the last time

that you will use them... As for their alleged propensity for attracting dust, this is not a concern if they are

regularly cleaned with a dry anti-static cloth made of micro-ﬁber, like the COKIN PRO cleaning cloth.

•

Handle the filters by holding them by their edges to avoid fingerprints as much as possible and keep

them in their individual sleeves when not in use. If you take care of them as you would your eyeglasses,

they will stay like new for years to come.

•

To tidy up the ﬁlters, use a dry air spray (held vertically) or a gentle non-static paintbrush.

•

For fingerprints or water smudges, wash the filter in warm water, then rinse it in lukewarm clean water and

dry sideways. Delicately remove possible residues from the lens with the cloth.

BELLOWS

MODULAR – FLEXIBLE – MAXIMUM PROTECTION

When shooting images, no matter what the medium in question – photo, video or cinema – ﬂare

remains a constant concern. Cameramen have long since mastered the problem with matte boxes,

“ﬂags”, and other light shading devices... Photographers who work in large format have also

always had a very useful shading tool: a bellows, which they carefully adjust before each trip of

the shutter. Hasselblad® has popularized this accessory in medium format and for years COKIN

has endowed its systems with excellent combinations of bellows and ﬁlter-holders (sometimes

called a “compendium”). The Z-PRO System includes this optional accessory which has become

rather indispensable, considering the extreme susceptibility of today’s digital sensors to ﬂare.

Side view

The Z-PRO bellows

is supplied with an in-

tegrated ﬁlter-holder that remains fully functional:

modularity (1, 2 or 3 slots, according to need), ﬂexible

manipulation and precise rotation.

•

The bellows is manufactured from a high-tech ‘form

memory’ material that doesn’t rely on support rails for

extension, limits the weight and obstruction of the

accessory

and allows for a higher degree of adjustability

(favoring one side, for example, in order to accomodate

the displacement of a view camera’s lens).

•

This “compendium” ensures, no matter what focal

length is used, a maximum protection against ﬂare,

the folds of the bellows being much better suited for

stopping rays of light than the interior coating of a

rigid lens hood.

•

Thanks to its compactness when closed and its superior

extendibility, this lens hood has

proven to be especially

versatile: in 6 x 7, it is suitable for lens focal lengths

from 50 mm to 250 mm. That means you only need a

single lens hood for several lenses!

•

To improve its anti-reﬂective action you can slide optional

mats onto the front of the bellows. They will allow you

either to further increase its effectiveness with telephoto

lenses (from 200 mm in medium-format), or to better

adjust the extendable section of the lens hood to your

photographic format (originally conceived for formats 4.5

x 6 and 6 x 7 cm, 4 x 5”; the two optional mats are intended

either for 6 x 6 cameras, or for 35mm or 6 x 9 formats).

With a bellows, the contrast and saturation of images are noticeably

improved and, most of all, the devastating effects of flare

– especially fatal in digital – are reduced to a minimum!

Combined with the High-Tech COKIN PRO cleaning cloth, it

blocks all entrance of ﬂare into the lens. Non-cumbersome

when closed and light (210 g), this modular bellows adapts itself

to all lenses (

up to 96mm in diameter), except to super wide-angle

lenses (risks of vignetting below 50mm in medium-format).

ACCESSORIES

INDIVIDUAL SLEEVE– MULTI-STORAGE

POUCH – CLEANING CLOTH

Certain seemingly unimportant

accessories are absolutely

necessary for the everyday

usage of ﬁlters, including

accessories relating to their

transport and cleaning.

Z-PRO individual cloth ﬁlter sleeves

Each Z-PRO ﬁlter is supplied in a separate, very

thin, suede-like cloth ﬁlter sleeve which comes in

a single size. It is lightweight and practical for use

both in the studio or outdoors. Inserted ﬁlters are

extremely accessible and, at the same time, very

well-protected. Each ﬁlter sleeve is marked with the

reference of the ﬁlter

it contains for rapid retrieval

of the correct ﬁlter.

A well-adapted solution to occasional use which

really limits the general burden of carrying a com-

plete set of ﬁlters.

dim. : 165 x 115 x 2 mm, 25 g (empty)

The Z-PRO multi-storage carrying-pouch

This padded, waterproof case is made of tough “900 deniers” nylon and hold up

to 7 ﬁlters, each individually protected by a soft, felt separator. Additionally, you

can store two supplementary adapter rings. A zipper allows for complete and

easy access. The inside of the carrying-case is detachable for other potential

use and it comes equipped with strap and a belt loop.

The Z-PRO multi-storage carrying-case is ideal for keeping all of the current

ﬁlters close-at-hand, always ready and always protected between shots.

dim. : 147 x 192 x 44~107 mm (w x h x d), 250 g (without filter), ref. Z306

The COKIN PRO cleaning cloth

Designed for the efficient but gentle cleaning of organic or mineral glass filters,

this cloth can also be used for all sorts of optics. Constructed from anti-static,

non-abrasive, non-shedding microfiber cloth (ultra-adept at capturing fine dust

particles), and absolutely free of chemical residues harmful to the filter’s optical

coating, it constitutes a real guarantee of longevity for your filters. It is machine-

washable and delivered in a protective carry-case.

Large in size (48 x 12 cm unfolded, 12 x 12 folded), this cloth can likewise serve

as added protection against flare pouring through the filter-holder slots or the

bellows itself: simply drape it over and its black color and opaqueness will block-out

extraneous light. Simple, practical, and rather clever!

dim. : 480 x 120 mm (w x l), ref. R908.
